Nah. Still nothing. According to Mac Rumors an update will fix it but when, nobody knows :/

tbh I heard only M1 will have it

Works with you too?

Got M1 MBP and iPad Pro 4th gen and nth. How's that possible?

It allows you to use your Macbook M1 MacOS 12 trackpad or mouse also on iPad iOS 15 if devices are next to each other. You simply need to swipe through the MacBook screen edge towards an iPad and the cursor will appear on it. No need for a second trackpad/mouse. Tim showed it during last event, it's on Youtube as well. You can also swipe files etc.
